Well there are 2 Somers events that Ed is involved with. One is the Snow Run Enduro on 1/27, and the other is Somers Fun on 8/18. I'm thinking the 8/18 ride would be best.
On a side note, if we don't get much more snow, you won't need spikes to do the upcoming Enduro. Last year was a blast and most people rode on regular tires.
